Abstract

ABSTRACT Since the last five decades, polymer-derived ceramics (PDCs) are in use and envisaged for a variety of applications. The transition of a precursor to an inorganic ceramic by pyrolysis and heat-treatment results in either amorphous or nanocrystalline composites with the evolution of phases strongly controlled by the processing conditions. Understanding the deformation behaviour under ambient conditions and at elevated temperatures is key to designing these materials for long-term use. However, quantitative reliable estimation of mechanical properties is quite challenging due to its unique structure which in turn is strongly governed by the precursor chemistry. The mechanical behaviour of PDCs in the form of fibres, bulk and foams are different and they are discussed separately. Both experimental and simulation-based studies are considered in this review. Recently, additive manufacturing processes have been used for the fabrication of PDCs, the mechanical properties of which are also included in this review.

聚合物衍生陶瓷的力学性能研究进展
摘要:在过去的五十年中,聚合物衍生陶瓷(PDCs)被用于各种应用。前驱体通过热解和热处理转变为无机陶瓷,得到非晶或纳米晶复合材料,其相的演变受加工条件的强烈控制。了解在环境条件下和高温下的变形行为是设计这些材料长期使用的关键。然而,由于其独特的结构又受前驱体化学的强烈支配,因此对其力学性能进行定量可靠的估计是相当具有挑战性的。纤维、体和泡沫形式的聚苯乙烯的力学性能不同,并分别进行了讨论。本综述考虑了实验研究和基于模拟的研究。近年来,增材制造工艺已被用于制造PDCs,其力学性能也包括在这篇综述中。
